Specification of Letters Patent.

Application filed March 4, 1915, Serial No. 12,079. Renewed October 18, 1919. Serial No. 331,742.'

To all whom it may concern:

' zen of the Republic of Colombia, and a resident of Bogota, Colombia, South America, have invented a new and Improved Typewriting-Machine, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a machine for automatically and serially printing a group of letters; to provide a machine for automatically shifting the lines to be printed; to provide means for augmenting the letter-printing capacity; to provide a key-board arranged for grouped printing; to provide means for augmenting and limiting the marginal width of sheets on which printing is to be executed; to provide a selective key-board disposed in accordance with a system wherein the consonants and vowels forming syllables are arranged in their natural order or sequence; to provide a platen whereon paper is arranged in fixed relation for affording increased facilities for proof reading the. printed matter prior to disturbing its relation to the printing mechanism of the machine; to provide a printing member having a multiplicity of alphabetic characters, sald characters being arranged in groups corresponding with the automatic action of the printing mechanism; to provide means for automatically shifting the line-printing, thus avoiding interruption of the manual manipulation of the key-board; and to provide a power-driven machine of the character mentioned. Y

The present machine comprises several groups of elements or instrumentalities cooperating to common ends. To indicate the association of each element in the assembled machine to one or other of these groups, the elements or instrumentalities of each group are assigned connoted designating numerals. Thus, numerals from 100 to 200 are employed for designating the instru- 'mentalities of what is herein termed the line-spacing mechanism; the numerals 200 to 300 are employed to designate the elements of the letter-spaclng mechanism; numerals from 300 to 400 are assigned to the elements of the printing mechanism; numerals from 400 to 500 designate the parts .of the operating mechanism; numerals 500 to 600 are assigned to the elements of the printing position controlling mechanism; and numerals 600 to 700 are employed for designating the "members of the power driving mechanism The machine herein disclosed is primarily employed to print by succesive automatic operations and in series, groups of letters forming words or parts of words. The arrangement of the letters is automatic and is the direct result of the design of a keyboard for operating the machine and a type wheel which corresponds therewith. It is preferred to conduct the operation of printing by selecting the keys and letters which form syllables. Where it is desired, the operator may at will select groups of letters without reference to their syllabic arrange-'.

I banks of keys are employed. Any number of letters may be printed in groups, but if the successive arrangement of the letters on the key-board does not correspond with the used, then the letter which does not conthe types would print als.

form in arrangement must be found in an upper or lower bankr Thus, if the letters 1, a, s, should be wanted, if they were used in a single bank To correct this,.the operator depresses the 1 in the upper bank and a and s in the lower bank. As hereinafter disclosed, the banks or groups of keys in the key-board have a counterpart arrangement in the printing type wheel. As a result, when the operator depresses the keys in the, manner set forth,

the automatic printing will follow the order of the banks, and the syllable las7 will be printed.

If the machine and the printing mechanism thereof are speeded, it is obvious that the length of time required for printing would be substantially curtailed.

Line spacing mechanism.

In the present machine the platen consists primarily of a cylinder 101. The cylinder 101, as shown best in Fig. 6 of the drawings, is hollow. The diameter of the cylinder 101 may be varied. The design is to have a circumferential dimension somewhat greater than the conventional width of paper used in business. The length of the cylinder 101 is slightly greater than the length of the paper referred to. The paper is secured upon the cylinder by clip bars 102. The bars 102 are of suitable width and have hinge lugs 103, tabs from the ends of which receive pivot pins 104. The pivot pin 104 on one bar 102 is permanently attached to the ends of the cylinder 101. The pin 104 of the other clip bar is permanently attached to an extension 105 set out from adjusting heads 106. The adjusting heads 106 are moved at will, the object being to accommodate papers of different sizes.

When introducing the paper on the cylinder, the clip bar 102 at the right of the" cylinder (at the-left in Fig. 4 of the drawings) is preliminarily lifted. The righthand edge of the paper is then introduced beneath said clip bar until arrested by a gage stop 107. The gage stop 107 is permanently attached to the clip bar 102-and determines the normal margin at the right of the paper. After the clip bar 102 at the right of the paper has clamped and firmly holds the same on the cylinder 101, the opposite clip bar 102 is lifted and the lefthand edge of the paper is sli ped thereunder. It is at this time that' he heads 106 are adjusted to the width of the paper which it is desired to use. The clip bars 102 are both held in service position by pull sprmgs 108, as seen best in Fig. 5 of the drawlngs.

' longer than the cylinder 101, being employed as a guide as well as a driving member for said cylinder. Said shaft extends through perforations provided in the heads of said cylinder and is rigidly mounted on a spindle shaft 110, with which a motor spring 111 is actively connected. The spring 111 is best shown in Fig. 10 of the drawings, togethenwith an anchor pin 112 for securing the same on a ratchet wheel 113, which is mounted on a socket post 114. At this time it should sufiice to state that the winding mechanism is provided for automatically winding said spring. The spring being wound, the cylinder 101 is constantly alert and under tension to rotate in one direction.

The cylinder 101 is supported rotatively in collars 115 and 116. The collars 115 and 116 are connected by means of bracket arms 117 with an upright bar 118. The bar 118 is provided at the outer edge with down-set ratchet teeth 119. With the ratchet teeth.

119, a pawl 120 pivotally mounted at the end of a rocking bar 121, engages. The rocking 'bar 121 is definitely pivoted by a pin which passes through an eyelet 122 at the end of said bar removed from the pawl 120. The pawl 120 is normally maintained in contact with the teeth 119 by a short fiat spring- 123, as seen best in Fig. 6 of the drawings. The pawl-provided end of the bar 121 is in turn supported by a lift-rod 124, with which it is connected by a sliding collar 125.

The rod 124 supports a spacing lever 126. The lever 126 is supported on the standard 127 by a curved rod 248. The lever 126 and the rod 124 are pivotally coupled by a pin 129. The rod 124 and lever 126 connected therewith are lifted by a spring 130 until arrested. by a stop bar 131.

I The lever 126 is provided with a ratchet head 132. The head 132 has a double-edged, ratchet-toothed extension, on one face whereof are formed teeth 133, and on the opposite face whereof are formedteeth 134. The member having the teeth 133 and 134 is separated from a smooth surface extension 135 by a standing flange 136. The flange 136 is inclined, as shown best in Fig. 7 of the drawings, and is designed as a deflector or guide for a pawl 137 to prevent the engagement thereof with said extension when the lever 126 is elevated. The pawl 137 operates as a feed member to engage the teeth 133 of the head 132. The pawl 137 has at its lower end a tooth adapted to engage the teeth 133 of the head 132, as best seen in F ig. 6 of the drawings. The pawl 137 is pivotally mounted on the free end of a
